Question

我正在尝试通过NuGet安装更新：

import xml.etree.ElementTree as et
import sys
import io
import string
import codecs

print("using texttool_navi.py" + sXmlFile)

#intializing Variables
sAddress = ''
sAcronym = ''
sPlace = ''
sData = ''

# parse texttool file
Parser =et
tree = et.parse(sXmlFile)
root = tree.getroot()

for child in root:
    if child.attrib["ID"] == sID:
        schild = et.tostring(child,encoding = 'utf-8')
        print('line ' + schild)
        sData = child.text
        sData = string.split(sData, '"')
        print(sData)
        sAddress = sData[1]
        sAcronym = sData[3]
        sPlace = sData[5]
        if sID == 'a specific ID':
            sAddress = string.replace(sAddress, '\\n', ' ')
            sAcronym = string.replace(sAcronym, '\\n', ' ')
            sPlace  = string.replace(sPlace, '\\n', ' ')

但是，更新永远不会成功，因为它在遇到以下冲突后回滚：

Microsoft.AspNetCore.Mvc 1.1.2 --> 2.0.4

因此，根据我的理解，Version conflict detected for Microsoft.CodeAnalysis.CSharp. Reference the package directly from the project to resolve this issue. Web -> Microsoft.AspNetCore.Mvc 2.0.4 -> Microsoft.AspNetCore.Mvc.RazorPages 2.0.4 -> Microsoft.AspNetCore.Mvc.Razor 2.0.4 -> Microsoft.CodeAnalysis.CSharp (>= 2.3.1) Web -> Microsoft.VisualStudio.Web.CodeGeneration.Design 1.1.0 -> Microsoft.VisualStudio.Web.CodeGeneration.Utils 1.1.0 -> Microsoft.CodeAnalysis.CSharp.Workspaces 1.3.0 -> Microsoft.CodeAnalysis.CSharp (= 1.3.0).是罪魁祸首，因为Microsoft.CodeAnalysis.CSharp具有依赖关系，要求它至少为Microsoft.AspNetCore.Mvc，而v2.3.1也有依赖关系它是Microsoft.VisualStudio.Web.CodeGeneration.Design

我不确定如何解决这个问题。它确实说v1.3.0但我真的不明白这意味着什么以及如何做到这一点。

Answer 1

如果直接添加依赖包（在这种情况下，将NuGet包Microsoft.CodeAnalysis.CSharp添加到项目中），Visual Studio将使用直接引用包的版本，而不是其他包的依赖关系中指定的版本。。这样，您已经指定了如何通过安装特定版本的依赖项来解决冲突。

您可以像其他任何NuGet软件包一样添加此引用：在VisualStudio中，右键单击项目->“管理NuGet软件包...”，搜索Microsoft.CodeAnalysis.CSharp并安装它。

如果您有用于还原所有Nuget的项目的“程序包”目录，则可以使用PowerShell脚本快速检查多个Nuget版本冲突：

$dir = "C:\packages"
$nugets = Get-ChildItem -Path $dir -Directory | ?{ $_.PSIsContainer } | ForEach-Object { $_.Name }
$nCount = $nugets.Count

Write-Host "Found $nCount nuggets in '$dir' direcotry"

$nugetObjects = $nugets | %{ [pscustomobject]@{ Name = $_ -replace '\.([0-9]).*([0-9])$'; Version = $_ -replace '^([A-Za-z]).*([A-Za-z])\.' }} | Group-Object "Name"

$conflicts = $nugetObjects | Where-Object {$_.Count -gt 1}
if ($conflicts.Count -gt 0) {
    Write-Host "Found Nuget multiuple versions"
    $conflicts
}
else {
    Write-Host "Jey - Not found any Nuget version conflicts"
}
